Tweedy is a family affair, seeing father and son team up for debut album Sukierae (released September 16).

While it was initially billed as a Jeff Tweedy solo project, the Wilco front man clearly grew to enjoy having his young fella at his side, and has now fully embraced the notion of a joint effort.

Still, they recruited help before taking to the Tonight Show stage; the awesome Holly Laessig and Jess Wolfe from Lucius (who play Ireland soon).

Check out the video of Tweedy and their friends performing 'High as Hello' below.
